Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 82, Mining.

Introduction
The ISO 22932 series has been prepared in order to standardize and to co-ordinate the global use of
technical terms and definitions in mining, for the benefit of the experts working on different types of
mining activities.
The need for the ISO 22932 series arose from the widely varying interpretation of terms used within
the industry and the prevalent use of more than one synonym.

Part 5:
Drilling and blasting
1 Scope
This document specifies the drilling and blasting terms commonly used in mining. Only those terms
that have a specific meaning in this field are included.
2 Normative references
This document does not contain normative references.
3 Terms and definitions
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1 Rock drilling concepts
3.1.1
back-reaming
enlargement of a bore by pulling back a tool of a larger diameter than that previously used to form the
bore
3.1.2
bench drilling
drilling (3.1.11) of blast holes (3.3.2) on benches (3.3.1) in open pit mines
3.1.3
blast hole drilling
drilling (3.1.11) of holes to be charged with explosive (3.25.1.4) for blasting (3.30.1.1)
3.1.4
consolidation drilling
drilling (3.1.11) of long holes in the front or at an angle of the drift direction to be injected with
consolidation fluid
EXAMPLE Grout (3.15.4).
3.1.5
coverage area
area that the rock drill can drill from one stationary position of the rock drill rig (3.8.15)
Note 1 to entry: The coverage area depends largely on the boom (3.13.11) configuration and if of the rock drill rig,
and if there is a turn able superstructure.
Note 2 to entry: Hole deviation (3.4.8) is due to the drill bit (3.11.1) changing direction as a result of, for example,
inhomogeneity in the rock or a bent drill rod (3.13.2) is bent. Hole deviation (3.4.8) can be minimised by sturdy
drill string (3.13.1) support and proper guidance while collaring (3.3.3).
3.1.6
dimensional stone drilling
drilling (3.1.11) of holes for quarrying natural stone
3.1.7
drainage drilling
drilling (3.1.11) of drainage holes for methane or water
3.1.8
drifting
drilling (3.1.11), blasting (3.30.1.1) and excavating rock to create transportation (3.16.16) and access
openings to ore bodies in an underground mining operation
3.1.9
drill instruction
instruction for how drilling (3.1.11) should be carried out
3.1.10
drillability
relative speed at which a material may be penetrated by a drill bit (3.11.1)
Note 1 to entry: High drillability denotes easy penetration at a fast rate.
[SOURCE: Reference [2]]
3.1.11
drilling
process by which a borehole is produced in any geological formation by rotary, rotary percussive,
percussive or thrust methods and in any predetermined direction in relation to the drill rig
[SOURCE: ISO 22475-1:2021, 3.1.5]
3.1.12
drilling for secondary breaking
drilling (3.1.11) of blast holes (3.3.2) in the boulders remaining after a blast
3.1.13
exploratory drilling
application of the mechanical engineering technology of deep drilling (3.1.11) to determine the profile
of the formation and retrieve strata samples to obtain the relevant geological parameters
[SOURCE: IWA 33-1:2019, 5.19]
3.1.14
face drilling
drilling (3.1.11) of blast holes (3.3.2) in the front wall at the end of a drift, rock chamber (3.22.6) or
tunnel
3.1.15
fan drilling
long hole production drilling (3.1.17) where the holes are drilled in the same plane but at different angles,
both left and right of vertical, to form a
